Associate Professor of Earth System Science, University of California, Irvine: [Ph.D. in Geological and Environmental Sciences from Stanford University].  Prof. Davis works to understand and find ways to meet the challenge of satisfying global demand for energy, food, and goods without emitting carbon dioxide to the atmosphere.
He is interested in studies of coupled human and natural systems and sustainable systems analysis, including: energy technology and policy; of pollution and resources embodied in international trade; of socio-economic inertia and “lock-in” of environmental problems; and of the complex interactions of energy systems, agriculture, climate change, and global ecology.
